Abstract

A communications module adapted to be received by an appliance having an appliance controller is provided. The module includes a communications protocol translator. The communications protocol translator translates signals received from a communications media into appliance controller signals. The translator also translates appliance control signals received from the appliance controller into a communications protocol to be output to an appliance communications network. A network ready appliance is also provided. The appliance includes an appliance controller having a communications port. The appliance also includes a cavity, defined by a plurality of walls, adapted to receive a communications module. An opening in a wall of the appliance allows access to the cavity. A connector is attached to one of the plurality of cavity walls. A communications line connecting the communications port and the connector is also provided. The connector is electrically coupled to the appliance controller or main power supply.

Claims

1. A communications module adapted to be received by an appliance having an appliance controller, said module comprising:

a module input/output (I/O) connector; and

a communications protocol translator connected to said I/O connector;

wherein said communications protocol translator translates signals received from said I/O connector into appliance controller signals to be output to said appliance controller and translates appliance control signals received from said I/O connector according to a communications protocol to be output on said I/O connector.

2. The communications module of claim 1 further comprising:

a power line transceiver connected to said communications protocol translator; and

a power line driver connected to said transceiver and said I/O connector,

wherein said appliance control signals translated according to said communications protocol are output from said protocol translator to said power line transceiver to operate said line driver to send the translated signals as power line carrier signals to a network.

3. The communications module of claim 1 wherein said I/O connector is adapted to be electrically coupled with an appliance power supply.

4. The communications module of claim 1 further comprising a second I/O connector and a modem connected to said protocol translator and said second I/O connector wherein said signals translated according to said communications protocol are output from said protocol translator to said modem for transmission to a network through said second I/O connector.

5. The communications module of claim 1 further comprising a radio frequency transceiver connected to said protocol translator wherein said signals translated according to said communications protocol are output from said protocol translator to said RF transceiver for transmission to an RF network.

6. The communications module of claim 1 wherein the protocol translator provides translation for at least one of EMIT, EHS, EIB, KNX, LonWorks, and Bluetooth communication protocols.

7. A network ready appliance comprising:

an appliance controller including a communications port;

a cavity, defined by a plurality of walls, adapted to receive a communications module;

an opening in a wall of the appliance providing access to said cavity;

a connector attached to one of said plurality of cavity walls;

a communications line connecting said communications port and said connector, and

a power supply,

wherein said connector is electrically coupled to said appliance power supply.

8. The network ready appliance of claim 7 further comprising a detachable cover provided over said opening.

9. The network ready appliance of claim 8 wherein said detachable cover is attached to a wall of said appliance and is outlined by one of perforations or scoring and wherein said cover can be detached from the wall by breaking said cover away from the wall.

10. The network ready appliance of claim 8 wherein said cover requires a tool to facilitate removal of said cover over said cavity.

11. The network ready appliance of claim 7 wherein said opening is sealed upon placement of said communications module in said cavity.

12. The network ready appliance of claim 7 further comprising a communications module connected to said connector attached to one of the cavity walls, said communications module including:

a communications protocol translator connected to said connector;

wherein said communications protocol translator translates signals received from said connector into appliance controller signals to be output via said connector to said appliance controller and translates appliance control signals received from said connector according to a communications protocol to be output to a power line via said connector.

13. The networked appliance according to claim 12 wherein said module further includes

a power line transceiver connected to said communications protocol translator;

and

a power line driver connected to said transceiver and said connector, wherein said signals translated according to said communications protocol are output from said protocol translator to said power line transceiver to operate said line driver to send the translated signals to a network as power line carrier signals via said connector and the appliance power supply.

14. The network ready appliance according to claim 7, wherein said connector is recessed in a second cavity.

15. A network ready appliance comprising:

a housing having a wall;

a cavity adapted to receive a communications module mounted on said wall;

an opening in said wall providing access to said cavity; and

a connector recessed in said cavity and connected to the base of said cavity,

wherein said connector is adapted to receive a connector of said communications module when said communication module is mounted on said wall thereby sealing said cavity and said recessed connector.

16. A network ready appliance according to claim 15, wherein said appliance further comprises:

an appliance controller; and

a communication line connecting said appliance controller to said recessed connector.

17. A network ready appliance according to claim 16, further comprising said communications module mounted on said wall, said module including a communications protocol translator connected to said recessed connector, wherein said communications protocol translator translates signals received from said recessed connector into appliance controller signals to be output via said recessed connector to said appliance controller and translates appliance control signals received from said recessed connector according to the communications protocol to be output to a power supply via said via said recessed connector.

18. A network ready appliance according to claim 17 wherein said module includes a connector attached a communications line that is inserted into said cavity to mate with said recessed connector.

19. A network ready appliance according to claim 18 wherein said module further includes a stem containing said module connector and communications line and wherein said stem is inserted into said cavity to mate said module connector and said recessed connector.
